RELATED APPLICATIONS AND CLAIM OF PRIORITY

This application is a continuation of and claims priority to U.S. patentapplication Ser. No. 15/786,282, filed Oct. 17, 2017, now U.S. Pat. No.10,143,053, issued Nov. 27, 2018, the disclosure which is fullyincorporated by reference.

BACKGROUND

Modern lighting systems include many features that were not previouslyavailable to facility operators and users. For example, lighting systemsthat include light emitting diode (LED) luminaires or other types ofluminaires may offer features such as: controllable dimming; colorselection and color tuning; adjustment of other characteristics ofemitted light such as color temperature or D_(uv) control of the shapeand/or direction of emitted light beams; and pre-programmed scenes orcustomized scenes that incorporate a set of pre-programmed features.

In facilities such as theaters, concert venues, sports fields andstadiums, and even in commercial buildings, the lighting needs canchange frequently depending on who is using the facility at any giventime. For example, a venue may be used for a convention or businessmeeting during the day and a concert or social event in the evening. Asports field may be used for a football or soccer game at one time ofday and a lacrosse team practice at another time of day. However,lighting systems do not easily adapt to the needs of each user andevent. Instead, lighting systems are typically set in a “fully on” or“fully off” arrangement unless the facility is staffed with technicianswho can manually change the lighting system scenarios in response to newusers' needs.

This disclosure describes methods and systems for controlling thefunctionality of a network of one or more lighting devices.

Additional elements that may be included inelectronic devices will be discussed below in the context of FIG. 7.

FIG. 1 illustrates a lighting device control system in which any numberof lighting devices 101, 102 are positioned at various locations in anenvironment, such as a wall, ceiling, mast, tower or other supportingstructure in a stadium, arena, concert hall, outdoor amphitheater, parkor other sports or entertainment facility, or a commercial building orother light-enabled facility. Optionally, a group of lighting devices atthe facility may be controlled by a gateway controller 104communicatively coupled to one or more fixture controllers 111, 112 thatare connected to one or more lighting devices 101, 102. If a gatewaycontroller 104 is used, it may be configured to pair with a portableelectronic device 103, receive a light operation request from theportable electronic device 103 and control at least one lighting device101, 102 via the fixture controller 111, 112 according to the lightoperation request. Alternatively or in addition, the portable electronicdevice may send control commands directly to a lighting device's fixturecontroller 111, 112. Each fixture controllers 111, 112 includes variouscomponents of an illumination device's control circuitry.

Each fixture controller, the gateway controller 104 and/or the portableelectronic device 103 may be capable of communicating with acommunication network 105, such as a cellular communication work, anInternet, a mesh network or other wired or wireless communicationnetworks. A remote server 106 also may be communicatively connected tothe communication network 105 so that it can communicate with theportable electronic device, gateway controller 104, and/or fixturecontrollers 111, 112. The remote server 106 may include or be connectedone or more memory devices that collectively store a database 108 ofdata for the light-enabled facility, such as scheduling data, data aboutavailable lighting devices and optional functions, available scenes,costs of various services and other data. The portable electronic device103 may include a memory device containing programming instructions thatare configured to cause the portable electronic device to performvarious functions. In addition or alternatively, the portable electronicdevice 103 may access the remote server 106 via a communication network105 to obtain program instructions that are stored on and/or executed bythe server.

Referring to FIG. 2, an example lighting device 101 will include anoptical radiation source, such as any number of lighting modules thatinclude LEDs, and in various embodiments a number of LED modulessufficient to provide a high intensity LED device. In variousembodiments, a lighting device may include multiple types of LEDmodules. For example, a lighting device may include a first type of LEDmodule 203 having LEDs that are configured to selectably emit whitelight of various color temperatures, along with a second type of LEDmodule 205 having LEDs that are configured to selectably emit light ofvarious colors. The lighting device 101 may include a housing 201 thatholds electrical components such as a fixture controller, a powersource, and wiring and circuitry to supply power and/or control signalsto the LED modules.

A fixture controller may be an external device or an integral devicethat includes various components of an illumination device's controlcircuitry. Example components of a fixture controller 301 are shown inFIG. 3. A fixture controller 301 will include a processor 302 and memorydevice 303 containing programming and/or data that the processor 302uses to selectively control the LED modules 310 or other opticalradiation source of the lighting device. The fixture controller 301 willinclude any number of communication interfaces, such as a Wi-Fi antenna304, a short-range communication or NFC transceiver 305, and/or a wiredcommunication interface 306 containing any number of ports 312 via whichother lighting devices, controllers or other devices may be connected tothe fixture controller's lighting device. For example, a gatewaycontroller 104 may be connected to the fixture controller 301 via any ofthe ports 312.

In this document the term “gateway controller” refers to a centralcontroller device that receives commands from a remote electronic deviceand routes the commands to appropriate lighting device fixturecontrollers in a network of lighting devices. The gateway controller mayinclude a processor and a communications interface that includes arouter or switch with one or more Ethernet ports or optical fiberconnectors configured to receive an Ethernet and/or fiber-optic cable.Other types of cables and connectors may be used, but for purposes ofthis disclosure Ethernet and fiber-optic cables and connectors will beused as examples. This document may use the term “lighting devicecontroller” to refer to a component when the component may be either agateway controller or a fixture controller.

Referring back to FIG. 1, a lighting device 101 may communicate with aproximate portable electronic device 103 via a direct or indirectcommunication link. The lighting device 101 also may communicate withany number of proximate additional lighting devices 102 via a direct orindirect communication link. Each of the lighting devices 101, 102, aswell as the proximate portable electronic device 103, may communicatewith a remote server 106 by any number of communication links. Theremote server 106 may be a cloud-based server that communicates with theother devices via a communication network 105.

FIG. 4 is a flow diagram illustrating a method of controlling one ormore lighting devices in a system such as that disclosed above. Alighting device's fixture controller, or a gateway controller if used,will detect 401 that a portable electronic device on which a lightingcontrol application is installed is proximate to the lighting device orgateway controller. Devices are “proximate” to each other if they arewithin a communication range of each other on a local area network orusing a short-range communication or NFC communication protocol.

Short-range communication transceivers are devices that directlycommunicate with each other via relatively short distances on the orderof 100 meters or less, or 10 meters or less. Examples of short-rangetransceivers include those that adhere to short-range communicationprotocols such as ZigBee®, Bluetooth®, and Bluetooth® Low Energy (BLE)transceivers, and/or via infrared (IR) light transceivers. NFCtransceivers are ultra-short range transceivers that adhere to one ormore standards for radio frequency communications that may be used whentwo devices are in close proximity, and may include hardware elementssuch as loop antennas that exchange information via electromagneticinduction. Protocols for implementation of NFC may comply with industrystandards such as ISO/IEC 18092 or ISO/IEC 18000-3, published by theInternational Standards Organization. Typical ranges for near fieldcommunications are approximately 10 cm or less, although it may be 20 cmor less, 4 cm or less, or other ranges. By receiving a connectionrequest via a short-range communication protocol or NFC protocol, thelighting device or gateway controller will thus detect that the mobileelectronic device is proximate to the lighting device.

This detection 401 may occur, for example, by receiving a connectionrequest from the portable electronic device via a short-rangecommunication or NFC transceiver. Alternatively, the detection 401 mayoccur by receiving a connection request from the portable device via aknown wireless local area network (WLAN), such as a Wi-Fi network thathas a limited range and to which the lighting device is alsocommunicatively connected. By receiving a connection request from amobile electronic device that is communicatively connected to the sameWLAN to which the lighting device controller is connected, the lightingdevice controller will thus detect that the mobile electronic device isproximate to the lighting device controller.

The lighting device controller will also receive, via the communicationinterface, a light operation request 402 from the portable electronicdevice. The light operation request will be one or more data packetsthat include one or more settings for one or more opticalcharacteristics of light that the optical radiation source of thelighting device or devices that are associated with the lighting devicecontroller and/or other communicatively connected lighting devices mayemit. The one or more optical characteristics comprise may includesettings such as a brightness or dimming level, color temperature,color, D_(uv), beam shape, and/or beam direction of the light emitted bythe optical radiation source. The lighting device controller maydetermine whether the portable electronic device is authorized to causethe lighting device(s) to implement the light operation request 403. Ifthe lighting device controller determines that the portable electronicdevice is authorized to initiate the light operation request, it willcause the optical radiation source(s) to emit light that exhibits theone or more optical characteristics of the light operation request 404.If the lighting device controller determines that the portableelectronic device is not authorized to initiate the light operationrequest, it will not implement the request and thus not activate theoptical radiation source(s) according to the request 405.

To determine whether the portable electronic device is authorized tocause the lighting device controller to implement the light operationrequest 403, the lighting device controller may determine whether theportable electronic device is associated with a valid unlock token forthe light operation request. A valid unlock token is a digitalidentifier that the lighting device knows represents authorization toactivate or change one or more characteristics of emitted light, such asa code or authentication token. The lighting device controller mayreceive the unlock token from the portable electronic device with thelight operation request and compare the token with a set of locally orremotely stored authentication tokens to determine whether the receivedtoken matches a known valid token or adheres to a valid token standard.Alternatively, the lighting device controller may receive an accountidentifier for the portable electronic device, transmit the accountidentifier to a remote server so that the remote server can perform theauthentication, and receive the unlock token from the remote server ofthe remote server determines that the portable electronic device isauthorized to unlock the requested feature of the lighting device.

To obtain an unlock token, the user interface may output indicia ofwhether an account associated with the portable electronic device hasunlocked an ability to adjust the user-selectable setting. The portableelectronic device may receive, via the user interface, a request tounlock a user-selectable setting for which the ability to adjust islocked. If so, the portable electronic device may transmit a command tocharge the account an amount that is assigned to the user-selectablesetting. Upon receipt of verification that the account has been chargedthe amount, the portable electronic device may unlock the ability toadjust the user-selectable setting and generate or receive the unlocktoken.

To cause a lighting device's associated optical radiation source to emitlight that exhibits the optical characteristics values of the lightoperation request 404, the fixture controller of that lighting devicewill implement one or more commands to control operation of the opticalradiation source. Example methods for altering optical characteristicsof LED lights are disclosed in, for example: (i) U.S. Pat. No. 9,188,307to Casper et al., titled “High Intensity LED Illumination Device withAutomated Sensor-Based Control”; (ii) U.S. Pat. No. 9,189,996 to Casperet al., titled “Selectable, Zone-Based Control for High Intensity LEDIllumination System”; (iii) U.S. patent application Ser. No. 15/670,659,filed by Nolan et al. and titled “Lighting Device LED Module withEffects for Color Temperature Tuning and Color Tuning”; and (iv) U.S.patent application Ser. No. 15/670,671, filed by Nolan et al. and titled“Lighting Device LED Module with Effects for Beam Spread Tuning and BeamShaping.” The disclosures of each of these patents and patentapplications are fully incorporated into this document by reference. Theoptical characteristics may include a scene, which is a set of datacorresponding to various optical characteristics of the emitted lightfor which the setting values will change over time. If so, then thefixture controller may cause the values of those optical characteristicsof the emitted light to change over time according to the scene.

Optionally, the light operation request may include a time. The time isa data point indicative of a numeric start time, stop time and/or or aduration for activation of one or more characteristics of the opticalradiation source. If so, then when causing the optical radiation sourceto emit light according to the requested characteristics the fixturecontroller will initiate or maintain the optical radiation source in anon condition according to the selected characteristics at a first time,and then when a time out condition occurs 406 corresponding toexpiration (i.e., the off time or the end of the duration), the fixturecontroller will deactivate the optical radiation source and/or theselected characteristics when the time expires 409. Deactivation mayinclude completely turning the light off, or returning the light to adefault setting that does not include all of the selected characteristicvalues of the light operation request. Optionally, the system mayreceive an extension request 407 from the mobile electronic devicebefore the time expires. The extension request will include a new (andlater) stop time or an extension to the duration. If the fixturecontroller determines that the mobile electronic device is authorized toextend the time of operation according to the extension request (usingauthorization procedures such as those described above), the fixturecontroller will continue to activate the optical radiation source 408with the requested characteristic values until the extended timeexpires, at which time the fixture controller will deactivate the lightas described above.

Optionally, a light operation request may include a request to operatenot only the lighting device that includes or is associated with thelighting device controller receives the request, but also one or moreother lighting devices in a system that is communicatively connected tothe lighting device controller that receives the request. For example,the light operation request may include one or more settings for one ormore optical characteristics of light that a second lighting device mayemit. To do this, the lighting operation request may include anidentifier for the second lighting device, such as an address of thesecond lighting device, or it may include a general command such as“apply the light operation request to all connected lighting devices.”If so, the lighting device controller may determine whether the portableelectronic device is also authorized to initiate the light operationrequest for the second lighting device, and if so the lighting devicecontroller will transmit one or more settings from the light operationrequest to the second lighting device for a fixture controller of thesecond lighting device to use in operation of its optical radiationsource. This transmission may occur via a wired or wirelesscommunication link. The requested optical characteristics for the secondlighting device may be the same as or different from those requested forthe first lighting device.

FIG. 5 illustrates an example portable electronic device 501 with userinterface 502. In the example of FIG. 5, the user interface 502 is atouch-sensitive display device. In other embodiments, instead of or inaddition to the display the user interface may include other userinput/output hardware such as a microphone and/or audio speaker, akeyboard or keypad, or another user interface device. The user interface502 may include a fixture selector 503 via which the user may select oneor more lighting devices to control, and a time selector 504 via which auser may enter a time 514 such as a start time, stop time or duration.The user interface 502 also may include any number of lightingcharacteristics selectors 505, 506 via which the user may enter valuesfor one or more user-selectable settings for characteristics of thelight to be emitted by the selected lighting device(s). The system maydisplay various candidate user-selectable settings 516, 517, 545, suchas a data entry field, a list of options or another selector, forcharacteristics that the user is authorized to select. For any settingsthat are locked for the user's account (i.e., not yet unlocked becausethe user is not yet authorized to implement the settings), theuser-selectable settings 516 may be displayed in a non-selectableformat, such as a shield or overlay, or in a greyscale or other formatthat is not actuatable by the user until the user unlocks the setting.The user interface also may include an actuator 521 via which the usermay unlock the setting, such as a purchasing interface by which a usermay purchasing access to the relevant feature.

Optionally, the user interface may include a scene selector 507 viawhich the user may select a scene that includes a set of one or morecharacteristics for one or more lights, in which the setting value forat least some of the characteristic(s) will change over time. Theavailable values 517 may include pre-defined scenes, or the system mayprovide a scene creator user interface via which the user may select thesettings, lighting devices and times that will define a new scene oradjust a pre-defined scene.

FIG. 6 illustrates a process that a portable electronic device mayfollow to initiate a light operation request for one or more proximatelighting devices. The portable electronic device will include a userinterface that outputs various candidate optical characteristics for theoptical radiation source 601. For at least some of the candidate opticalcharacteristics, the user interface will also display user-selectablesettings. As discussed above in FIG. 5, the system also may outputlock/unlock status indicia 602 of whether an account associated withportable device or its user has unlocked the ability to select settingsfor each characteristic. For example, for characteristics that are notlocked, user-selectable settings may be presented in a user-selectableformat, such as a data entry field, list, or other structure.Characteristics for which user-selectable settings that are locked willnot be displayed in a user-selectable format, and may be displayed ingrayscale, in shielded format, or with other indicia showing that theyare locked, or they may not be displayed at all.

For any characteristic that is locked, the user may input (and theportable electronic device may receive via the user interface) an unlockrequest 603. If so, the system may generate and transmit a command tocharge a user's account an amount required to unlock the setting 604.Upon receiving confirmation from the remote server that the account hasbeen charged, the device may unlock 605 the characteristic so that theuser can select the value of that characteristic's setting.
